``solid-blob test'' -- run tests on solid-blob extract

purpose:

This is a test function. It is identical to ``solid-blob extract'' except that this function allows one to test the impact of varying individual parameters.

A chosen parameter is varied a number of times (as specified by ``number of iterations = '') using a specified increment (as specified by ``amount to increment parameter = ''). The function ``solid-blob extract'' is run for each value of the parameter. Each run generates an output volume called, for example, filename_v7, where filename is the name of the input volume and the prefix ``_v7'' indicates that the volume filename_v7 corresponds to the seventh iteration of ``solid-blob extract''.

Run this function in background mode!

input:

An 8-bit volume.

output:

A sequence of 8-bit volumes, one for each iteration. Also, the file ``invol.size'', which gives the sizes in voxels of the extracted regions; ``invol'' is the name of the input volume. One set of sizes will be in this file for each iteration of solid-blob test. If no input volume name is specified, a file called ``sizeXXXXXX'' is made, where XXXXXX is a computer-generated code like g56038.

parameters:

Default parameters menu is

param. to vary= attachment diameter
amount to increment parameter = 1
no. of iterations = 1
smallest isthmus diameter = 7
use papillary muscle probe = yes
No. of objects to save = 1
clean up areas straddling zeros = yes
use maxh filter = yes
thresholding scheme = auto threshold
*****Auto-thresholding Parameters*****
mode = restrict rise
top-level parameters:
lowest tolerable threshold = 120
cue-slice number = 1
# of slices per group = 2
max intergroup threshold change = 30
max allowed threshold rise(RR mode) = 5
use area-of-interest (mbc) analysis = no
area-of-interest expansion factor = 100
histogram-analysis parameters:
min histogram peak sep (graylevels) = 30
min histogram-peak area(% of total) = 2.00
absolute min peak sep = 16
****Manual-thresholding Parameters****
FIRST threshold:
threshold = 0
beginning slice = 0
SECOND threshold:
threshold = 0
beginning slice = 0
input from vol # = 0
copy output to vol # = 0

The parameter ``param. to vary = '' , which toggles, set the parameter to vary during iterations. The parameters ``amount to increment parameter = '' and ``no. of iterations = '' also control the set up of a test. All else is identical to ``solid-blob extract''.
